Sphere lighting Posted July 5, 2018 Share Posted July 5, 2018 Hi All, Looking for some advice. I am working on an installation, and the design notes that the IWB's are to be welded in place to the brackets. I have never seen nor herd of an IWB to be welded, and I always believe that they should be installed so they can be maintained in future, meaning a non perm fixing. The location of this bar will be mounted to a wall. Please advise on this topic. Matt Link to comment Share on other sites More sharing options...
timsabre Posted July 5, 2018 Share Posted July 5, 2018 You need to contact the designer to clarify what they were thinking... I've never heard of it either but if it's specified there must be some reason. Link to comment Share on other sites More sharing options...
kerry davies Posted July 5, 2018 Share Posted July 5, 2018 It looks like someone doesn't fully understand that applying heat to a metal tube containing power cables is a "notagoodthing". I also wonder how many TIG welders out there could actually weld thin walled aluminium tube to steel brackets anyway.Best ask the questions first I think.

Yes I have worked on some fully welded IWB's including ali mounting hardware which had to be re-wired in situ. Additionally IWB's can also be made with steel scaff.

Dave m Posted July 7, 2018 Share Posted July 7, 2018 Well you can weld an alli bar to an alli bracket but you can't weld a bracket to a wall , so it will be removable, if chuffing awkward.I am sure that I remember C shaped bars that had a plastic insert so you could easily add extra cable? Why welded? If it is because the bracket position means that he is worried about "droop" then a ladder type bar can be used Link to comment Share on other sites More sharing options...
jonathanhill Posted July 7, 2018 Share Posted July 7, 2018 I am sure that I remember C shaped bars that had a plastic insert so you could easily add extra cable? Furse used to manufacture their IWBs like this. Fine until someone winds the wing bolt of a hook clamp through the plastic and into the wires.
